I thought I would update this thread with a progress report. In short, I'm much closer to my goal! The above recipe produces a wonderful bitter. I made the above recipe exactly as written, and shortly after, I made the recipe again but with the 15 minute hop addition moved to a 15 minute steep at 80C, with an appropriate increase in the bittering charge to get the same IBUs.
The wlp005 worked great, I love the flavors it produces and that got me closer to the beer I wanted than anything else. I do have a problem with it stopping at 1.015 despite repeated rousings. I may try a semi-open fermentation for the next batch as I've heard that can help this strain.
The flavor is great on both beers, but I defintely prefer the second iteration, but I'll get to the hops later. That maltiness I was looking for really made an appearance here. Light toffee/butterscotch flavors really shine and are exactly what I'm looking for. The hop bitterness is just right and the hops round out the flavor. And the wonderful ringwood esters pull everything together.
Now on to the hops. The first recipe, with 20g of Goldings at 15 minutes, has a strongish hop flavor that competes somewhat with the malt flavors. Hop aroma for that recipe is very slight. The second recipe, with the 20g Goldings being steeped post-boil, has a much smoother hop flavor that complements, rather than competes, with the malt. It also has a wonderful floral hop aroma that plays well with the esters and toffee aromas. It is definitely the one I prefer.
I'm going to keep brewing variations of this recipe until I've matched it to my tastes completely. Changes I would like to make in the future are:
1. Get it to dry out to 1.010 or so. To do that I'll play with semi-open fermentation as I mentioned above. Please note I'm pitching large, healthy starters, oxygenating for 2 minutes with pure oxygen through a stone, adding nutrient to the boil, etc. so the under-attenuation is not that. If the open fermentation doesn't work, I'll substitute a bit of brown sugar for the base malt (which should help with change 2).
2. I'd like it to be a bit darker. Right now it's a beautiful vibrant gold, but I think I would like a bit more richness to the color. Something that makes you expect the great toffeish flavors before trying it. The brown sugar listed above would probably help a little, but I may need to increase the pale chocolate slightly, perhaps even to 100g. I'm not detecting it much in the flavor now, though if I compared the beer to the same recipe without the pale chocolate, it would probably become evident.
3. Get more of the ringwood character into the final beer. I found that during active fermentation and early gravity tests, the ringwood character came through strongly. After several rousings and sitting on the yeast cake after fermentation, the flavors seemed to "clean up" a bit. Hopefully I'll get the beer to attenuate quickly next time so I can get it off the yeast before it cleans up too much. I like a little diacetyl in this recipe.
So that's where we are. I'll post a picture soon and continue to update the thread as I progress with this project.
EDIT: Oh, I forgot to mention that the first recipe used Crisp MO and the second used Thomas Fawcett. I'll have to compare the two back to back a little more to try to pull out the differences.
